The Rapid-Punch consists of a razor sharp cutting tip designed to cut, retrieve and store cored samples from source materials such as tissue, gels, paper, cloth, leaves, paint chips, films or other thin substrates. The Rapid-Punch is recommended as the special DNA sampling tool. It is ideal for forensic and most laboratory sampling purposes. Designed for heavy, numerous and precise sampling operations. It is durable, lasting up to 2000 punches.

Taking Forensic Samples

  1. Place the sample material on the self-healing cutting mat. The source material could be tissue, gels, paper, cloth, leaves, paint chips, films or other thin substrates.
  2. Remove the cap from the tip of the biopsy punch. 
  3. Position the tip perpendicular to the sample material so that the punch is vertically straight above the material. DO NOT PRESS THE PLUNGER. 
  4. Firmly hold the punch and press the tip downward into the source material until you feel the punch touch the cutting mat. 
  5. The cored sample will remain inside the punch as you lift the punch from the cutting mat.
  6. To eject the sample, position the tip of the punch over the area where you want to deposit the sample. Then, depress the plunger on the punch.

NOTE: After taking a sample, you may lay the punch down without fear of losing your sample. The sample remains safely inside the punch tip until you eject it. 

Taking Biological Samples

  1. Prior to taking biological tissue samples, tissue is usually shaved into 1-2 mm thick slices. Our Integraslice Vibrating Microtome (# CA5100MZ or CA5100MZ-PLUS) or our Brain Matrices may be used for this purpose. 
  2. Place the samples in a petri dish with an absorbent paper soaked in saline solution. Or, you can place the tissue on an ice-cold dissection plate.
  3. Take samples using the same procedure used for taking forensic samples.
  4. Eject the sample by depressing the plunger on the punch.

Ejection and Storage of Samples

The sample is briefly stored in the hollow cutting tip after coring, ready for the intended ejection method. The punch kit can be set on its side, and the sample from the hollow tip will not be lost. Position the tip over the target area and depress the plunger to discharge the sample.

Cleaning

Clean the tip every time you take a sample. 

  1. To clean the punch, core blank filter paper.
  2. Rinse the punch with ethanol. If your sample was dry, you could spray the punch with compressed air to remove any remaining debris. 
  3. Rinse mat thoroughly with ethanol after you take a sample.

If your cleaning protocol calls for you to clean the entire punch, completely disassemble it and use a mild, pH-neutral detergent (preferably using an ultrasonic cleaner). Before reassembling WPI Reusable Rapid Punch ensure all components are completely dry. Avoid non-neutral detergents as they can damage the punch.

Construction

The aluminum barrel of each biopsy punch is machined from high grade 6061-T6. It is lightweight, seamless, aluminum tubing. Because they are anodized to form a protective coating, the punches are chemically resistant and have a long lasting finish for easy handling. Punches include a deluxe plastic case.
